avast crashes my internet

for some reason, avast won’t let me play an online game for more than 15-20 minutes because it crashes my internet. I know this because I have disabled avast when I was playing an online game and everything went fine. can someone help me because I don’t want to switch to another AV?

I’m using avast free and win 7 x64

I have win7 64-bit too and all seems to be fine. If it crashes your internet this often, I suggest disabling your network shield while doing important stuff on the web. There might be something wrong with your wi-fi in terms of compatibility.

hey are you using the latest version of avast 8.01489?

any other security programs on your computer like third party firewall?

yes, I have the latest version of avast and I’m using comodo as firewall.
the problem stopped after disabling avast (and enabling it again) but what should I do if the problem comes back?

Make sure that avast! is allowed access to the internet through the Comodo firewall.
